Description

Technical Field

[0001] This utility model relates to the field of metal cover processing technology, specifically to a processing equipment for anti-slip textures and threads on metal covers. Background Technology

[0002] Metal caps typically require a threading process to form threads. This process involves a rotating threading roller rolling the surface of the metal cap while moving in one direction, creating threads on the inner side of the cap. This allows the cap to be secured to the bottle via these threads. Next, a stamping or embossing process is used to create anti-slip textures. The stamping process subjectes the cap to significant deformation in a single operation, making it prone to warping. The embossing process, on the other hand, involves a rotating embossing roller with gear-like teeth that rolls the cap's surface. This creates a ring of anti-slip texture on the cap's surface, increasing its roughness and making it easier to turn.

[0003] Based on the above, Chinese Patent No. CN218693502U discloses an apparatus for thread rolling of caps, including a base, a connecting frame disposed on the base, and a thread rolling device disposed within the connecting frame. The thread rolling device includes a first thread rolling wheel and a second thread rolling wheel disposed vertically on the connecting frame. A swinging device is connected to the rear end of the first thread rolling wheel within the connecting frame. A pin device coaxial with the second thread rolling wheel is provided on one side of the base, and a material ejector device coaxial with the second thread rolling wheel is provided on the other side of the base. A material support device extending towards the material ejector device and the second thread rolling wheel is provided at the front of the base. The apparatus uses the first and second thread rolling wheels to press the inner and outer surfaces of the cap, while the material ejector device gradually pushes the cap into the thread rolling device, thereby forming threads on the cap.

[0004] Chinese patent CN108097780A discloses a bottle cap anti-slip strip stamping device, including a workbench and a bottle cap. A side plate is welded to the rear of the workbench, and a fixed plate is connected to the front of the upper end of the side plate. An air pump is bolted to the top of the fixed plate, and a telescopic rod is connected to the bottom of the air pump. The telescopic rod passes through the fixed plate and connects to a fixed frame. The fixed frame has a lower opening, and a stamping frame is installed in the lower opening. A stamping port is opened inside the stamping frame, and a stamping strip integrated with the stamping frame is provided in the stamping port. A connecting post is welded to the top of the workbench, and the bottle cap is threaded to the connecting post. The connecting post is located directly below the stamping port. This device processes the anti-slip texture on the bottle cap by stamping.

[0005] The threads and anti-slip textures of metal covers are commonly processed using the two processing devices mentioned above. Based on the application scenarios of metal covers, threads and anti-slip textures are essential. Too many processing steps for metal covers will affect their processing efficiency, and there is still room for improvement in the processing efficiency of metal covers. Utility Model Content

Detailed Implementation

[0024] The embodiments of this utility model will be described below with reference to the accompanying drawings and related examples. The embodiments of this utility model are not limited to the following examples, and this utility model relates to relevant necessary components in this technical field, which should be regarded as well-known technology in this technical field and can be known and mastered by those skilled in this technical field.

[0025] like Figure 1-5 As shown, a processing device for anti-slip texture and thread on a metal cover includes a processing mechanism 1, a fixing mechanism 2, and a supporting mechanism 3. The processing mechanism 1 is located above the fixing mechanism 2. The processing mechanism 1 includes the following structure: a processing roller 11, the surface of which is provided with a plurality of anti-slip textured pressure blocks 12 and a spirally wound threaded pressure strip 13; both ends of the processing roller 11 are movably connected to an upwardly extending downward pressure bracket 14 by a shaft; a first motor 15 is provided on one side of the downward pressure bracket 14; the output end of the first motor 15 is movably connected to the end of the processing roller 11; the first motor 15 drives the processing roller 11 to rotate through the output end; and a downward pressure push rod 16, the movable end of which is fixedly connected to the top of the downward pressure bracket 14.

[0026] The fixing mechanism 2 includes the following structure: a fixing roller 21, the surface of the fixing roller 21 is provided with a plurality of anti-slip grooves 22 that match the anti-slip pressure block 12 and a threaded groove 23 that matches the threaded pressure strip 13, and a second motor 24 is provided at the end of the fixing roller 21. The second motor 24 drives the fixing roller 21 to rotate through the output end.

[0027] The support mechanism 3 includes a fixed base 31 fixedly connected to the second motor 24 and a fixed bracket 32 ​​extending upward to a fixed end fixedly connected to the lower push rod 16. The support mechanism 3 is used to fix the processing mechanism 1 and the fixed mechanism 2 and provide necessary support force. The fixed end of the lower push rod 16 is fixedly connected to the top of the fixed bracket 32. The movable end of the lower push rod 16 extends downward from the bottom of the fixed end. The lower push rod 16 is preferably an electric push rod. The lower push rod 16 pushes or pulls the lower support 14 through the movable end, so that the processing roller 11 reciprocates in the vertical direction.

[0028] This invention can simultaneously process anti-slip textures and threads on the surface of a metal cap. The metal bottle blank to be processed is placed on the surface of the fixed roller 21 by a robotic arm or manually. The threaded pressure strip 13 and the threaded groove 23 are both close to the opening of the blank, and the anti-slip texture block 12 and the anti-slip texture groove 22 are both close to the closed end of the blank. When processing begins, the first motor 15 drives the processing roller 11 to rotate, and the second motor 24 drives the fixed roller 21 to rotate. The processing roller 11 and the fixed roller 21 rotate at the same speed and in opposite directions. The downward push rod 16 moves and pushes the downward support 14 through its movable end. Under the action of the downward support 14, the processing roller 11 moves downward toward the fixed roller 21 until the anti-slip texture block 12 and the threaded pressure strip 13 are both in contact with the surface of the blank. The anti-slip texture block 12 forms anti-slip textures on the surface of the blank, and the threaded pressure strip 13 forms threads on the inner side of the blank.

[0029] Furthermore, the processing roller 11 is located above the fixed roller 21, the anti-slip pressure block 12 and the threaded pressure strip 13 both protrude outward on the surface of the processing roller 11, and the anti-slip groove 22 and the threaded groove 23 both recess inward on the surface of the fixed roller 21.

[0030] Based on the above structure, the principle of this utility model for processing anti-slip texture on metal cover blanks is as follows: a number of anti-slip textured blocks 12 are distributed in a circular array on the surface of the processing roller 11. The number of anti-slip textured blocks 12 will press the surface of the blank one by one and indent it to form a number of grooves. A number of protrusions will be formed on the inner side of the blank and will be embedded into a number of anti-slip textured grooves 22 one by one. After the processing roller 11 rolls the blank one or several times, a number of grooves distributed in a circular array will be formed on the surface of the blank. These grooves together form anti-slip texture.

[0031] Based on the above structure, the principle of thread processing of the metal cover blank in this utility model is as follows: Because the threaded strip 13 is spirally wound on the surface of the processing roller 11, as... Figure 3 As shown, the surface of the processing roller 11 is unfolded so that the threaded pressure strip 13 is located on the same horizontal plane. The threaded pressure strip 13 is composed of several inclined and raised pressure strips 17. Based on this structure, during the rolling process of the processing roller 11 on the blank, the rolling path of the threaded pressure strip 13 on the blank is an inclined line that matches several raised pressure strips 17. After the threaded pressure strip 13 rolls the blank once, these inclined lines will be connected end to end to form a spiral winding line along the surface of the blank. Since the threaded pressure strip 13 rolls the blank, it will cause the blank to be concave inward. At the same time, the inner side of the blank is raised in a relative position and embedded in the threaded groove 23, thereby forming a spirally extending internal thread on the inner side of the blank.

[0032] It should be further explained that the axis of the fixed roller 21 has a material feeding through hole 211 through it. The inner diameter of the material feeding through hole 211 gradually increases from one end near the second motor 24 to the other end. The fixed roller 21 is composed of two adjacent fixed blocks 212. A tension spring 213 and a material feeding push rod 25 are provided between the two fixed blocks 212. The two ends of the tension spring 213 are fixedly connected to the two fixed blocks 212 respectively. The material feeding push rod 25 passes through the material feeding through hole 211. The material feeding push rod 25 is preferably an electric push rod. The outer diameter of the movable end of the material feeding push rod 25 matches the inner diameter of the material feeding through hole 211.

[0033] This invention uses two fixed blocks 212 to assemble a fixed roller 21 with a cylindrical outer surface. The two fixed blocks 212 have spring holes that match the tension spring 213, allowing the tension spring 213 sufficient room to contract. The end of the tension spring 213 is fixedly connected to the bottom of the inner side of the spring hole. The two fixed blocks 212 are fixed into the fixed roller 21 by the tension provided by the tension spring 213. At this time, the outer diameter of the fixed roller 21 is smaller than the inner diameter of the blank, allowing the blank to be smoothly fitted onto the fixed roller 21 from the end. Then, the push rod 25 moves, causing its movable end to move towards the second motor 24. Because the inner diameter of the push hole 211 near the second motor 24 is lower, the two fixed blocks 212 are squeezed together by the movement of the push rod 25, moving away from each other, and the tension spring 213... The blank is stretched, increasing the outer diameter of the fixed roller 21 until its surface abuts against the inner wall of the blank, thereby fixing the blank. Then, the blank is processed with threads and anti-slip textures through the aforementioned steps. After the metal cover is processed, in order to avoid the difficulty of the blank separating from the fixed roller 21 due to the threads of the inner wall of the metal cover blank embedding into the thread groove 23, the movable end of the push rod 25 is reset. During this process, the two fixed blocks 212 will move relative to each other under the action of the tension spring 213 contraction and the resulting tension until they abut against each other. At this time, the fixed roller 21 is in a closed state, which reduces the outer diameter of the fixed roller 21 and thus cancels the fixing of the metal cover. As the movable end of the push rod 25 continues to move, its end end will abut against the closed end of the fatigued inner wall and push it away from the fixed roller 21, thereby separating the blank with completed threads and anti-slip textures from the fixed roller 21.

[0034] like Figure 1 As shown, in one of the preferred embodiments of this utility model, a transmission mechanism 4 is provided between the output end of the first motor 15 and the end of the processing roller 11. The transmission mechanism 4 includes the following structure: a drive gear 41, which is fixedly connected to the output end of the first motor 15; a transmission gear 42, which is movably connected to the lower pressure bracket 14 through a shaft and meshes with the drive gear 41; and a driven gear 43, which is fixedly connected to the end of the processing roller 11 and meshes with the transmission gear 42.

[0035] The first motor 15 of this invention is located above the processing roller 11. The transmission mechanism 4 drives the first motor 15 to rotate the processing roller 11 through gear meshing. When the first motor 15 is running, it directly causes the drive gear 41 to rotate. The rotating drive gear 41 meshes with the drive gear 42 and the driven gear 43 in sequence. The shaft of the driven gear 43 is fixedly connected to the shaft at the end of the processing roller 11, so that the processing roller 11 and the driven gear 43 rotate synchronously. Thus, the first motor 15 provides driving force for the rotation of the processing roller 11 through the transmission mechanism 4.

[0036] As one of the preferred embodiments of this utility model, the surface of the top push rod 25 is fitted with a drive sleeve 26 which is fixedly connected to the drive end of the second motor 24. The drive sleeve 26 is located between the fixed roller 21 and the second motor 24. The fixed end of the top push rod 25 is fixedly connected to the drive sleeve 26 and the movable end extends into the top through hole 211.

[0037] The drive sleeve 26 of this utility model is sleeved on the outer surface of the fixed end of the top push rod 25, so that the movable end of the top push rod 25 has sufficient space for movement. The fixed base 31 is movably connected to the drive sleeve 26 through an upwardly extending support plate. A bearing is provided between the support plate and the drive sleeve 26, so that the second motor 24 can normally make the drive sleeve 26 rotate.

[0038] With the above structure, it should be further explained that the fixed assembly 212 is provided with a groove 27 on the side near the drive sleeve 26. The extension direction of the groove 27 is the same as the tension direction of the tension spring 213. The drive sleeve 26 is provided with a slider 28 extending into the groove 27. The drive sleeve 26 is movably connected to the fixed assembly 212 through the slider 28. The drive sleeve 26 is embedded in the groove 27 through the slider 28, providing vertical support for the fixed assembly 212. During the operation of the push rod 25, the fixed assembly 212 can slide through the groove 27 and the slider 28 to change the outer diameter of the fixed roller 21.

[0039] In summary, this invention uses a fixed roller 21 to fix the metal cover blank to be processed and a processing roller 11 to process the blank with threads and anti-slip textures. During the processing, several anti-slip texture pressing blocks 12 will press the surface of the blank one by one to form an anti-slip texture composed of several grooves. At the same time, the thread pressing strip 13 rolls the surface of the blank to form several inclined and extending protrusions on the inner wall of the blank. These protrusions are connected end to end to form a spirally extending internal thread. This invention can form anti-slip textures and internal threads simultaneously by a single rolling of the metal cover blank by the processing roller 11, thereby improving the processing efficiency of the metal cover.

[0040] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
